ANSWER
Find out the how many cans does each one have.
To proof
As given
Amelia and Elliott are collecting empty soda cans for recycling
Amelia has 13 less than 5 times the cans that Elliott has.
let us assume that the Elliott has can be =x
Amelia can = 5x -13
Total can = 257 cans
than the equation becomes
x + 5x - 13 = 257
6x = 257 +13
6x = 270
x = 45
Elliott has can be = 45cans
Amelia can = 5 × 45 - 13
= 212cans
Hence proved
Answer:
The inequality range of X is determined as 5 < X < 9
Step-by-step explanation:
Given;
first length of the triangle = 2 inches
second length of the triangle = 7 inches
third length of the triangle = X
From the third length rule of a triangle, the following inequality range will be applied to determine the length of "X";
The third length of the triangle must be greater than the difference of the two known sides BUT less than the sum of the two known sides.
(7 - 2) < X < (7 + 2)
5 < X < 9
possible values of X = 6, 7, 8
Therefore, the inequality range of X is determined as 5 < X < 9
